To all wnomit may concern." i

Be it known that I, Josnrrr H. SEBALD, av citizen of the United States; anrl a'resiclent of Easton, county of Northampton, State of Pennsylvania, have invented certain new and useful Improvements in Valves, of

u specification.

This invention relates to valves for blow ing'engines, comprcssors, pumps and the. like, p iirticnl:irly tlumenpereting at high speeds. I i i One of the-objects ofutheinvention is to provide a mivc,-the spring-"ofwhich will noteause a rotation efthc valve es the lat ter cpens end closes, and which, at the same time, will be suilicientl'y yielding-and elastic to permit the rapid operation of the valvef- With; this and. other objects in View my: invention consists of certain novel features of constrilotiom combination and arrangement of parts, as will be more fully de-. scribed, and pointed out in the appended. claims 1 the drawings, Figure 'lirepresents'i a] plan and Fig. 2 at sectionalelevationbfi one form of my inventioni'liwhich the valvegtnd spring ere obsepnrnte pieces fastened to ether' %ig. 3 is a plan and '4: a sectional form of my invention 111 are integral";

In connection with my novel construction I am. enabled, to make the springhnd'velve of} two parts, if I sojdeslr'e, so that the spring itself may be made-56f, nym ii l 1 suitable :Eor the spring regardless materials or thickness of {parts necessary Broadly speaking, my spring com a support ng member, usually provide a centrzil opening by with which itmny be monnt-' ed on the valve seat,.-thi ssnpporting member being proyided with a pair ofmembers on each-side of and integral; with it, the ends rises of the side members bGIIIgaCOm QCtQd tothe Such a connected to i the valve preferably ends of the supporting member. spring is suiteb1e'manner fer'ably' by spptf welding,"as'indici'althd T in g in the member 10 invention; e.

It will be understood that'any other means of fastening the central member to the valve seat may be provided. As shownin Fig. 2, when the valve is closed, the spring is flat. As the valve 13 opens, as for instance, by moving rin upwardly in Fig. 2, the central portion of the member 10 being held 'fixed, the parts 10, 11 and 12 will'be distorted, but by reason of the connections of the .melbers 11 and 12 with each end of the member 10, there. will be no rotative movement given to the valve ring', but the latter will move straight u ward from} its seat.

- In the orm shown in Figs. 3 and 4, the spring is of the same shape as that shown in Fig. 1, but is formed integral with the valve itself. In this form the valve rin 18 an the circular members 19 and 20 an the supporting bar 21 are allstamped from the same sheet metal platen The action of this valve, when opened, isprecisely the same as that of Fig. 1, but in the form shown in F' 8 it necessarily follows that it is impossib e to make the springitself of diflerent material from that of the valve rin In Figs. 5, 6' and I have s own a formof my invention by which two springs may four inwardly extending-mam are 23, 24, 25

be used. The valve ring 22 is rovided with and 26, and a s ring is located on either side of the valve. he upper spring has the central supporting member 27, and the two circular side members 28 and 29, the member 28 being s ot welded to the arm 23 and the member 29 eing spot welded to the member 25. The bottom spring has the supporting member 30 and the circular side membars 31, 32, the side me'nlber 32 being spot welded tothe member 26 and the side member '31'to=the member 24.

Fig.6 shows in cross section the position 'of'these s rings when the valve is closed.

Fig. 7 s ows the position when the valve is open. It will be understood that proper means are providedbywhich the centers of the supporting members 27 and 30 are held the proper distance apart as shown in Fig.

6, and m Fig. 7, the various parts of the spring are shown in the positions approxis matel which they will occupy when the valve as moved upwardly ofl its seat.

, While m this form of; my invention I We fer-to provide the four. arms 23-26,- it will be ObVlOllS that instead of setting the supporting arms 27 and 30 at right angles to each other, the may be one directly over the -other, in whic 6D- case the spot welding will occur on the opposite sides of apair ofoppositely disposed members extending in-' wardlv fom the valve rin 22, in which event only two of such mem ers willb'e reqinred. 1 Figs. 8 and 9 I have shown a form of -/ta i' id except by the arrangement indicated in'Fig. 8.

In this form of valve if the valve rings have any considerablemotion away from the seat, it may be desirable jto s ace the spring vertically away fronrthe" va ve ring in Fig. 9 so as to prevent-the inner ring 35 from striking the supporting member 36, and thus preventing the proper flexing of the spring. Such spacin can be accomplished, of course, by anysuitaile spacing member between the spring and valve at the point-of connection between them.

In Fig. 10 I have shown another form of sprin which could be used with many forms of va ve, particularly that shown in Fig. 1.

illustrative forms of my invention would be cially in relation to the usual circular valve, it will be obvious that such a form of spring, as is shown in Fi 10, will accomplish the same results. In t is form the central member 41 is separated from the side members 42 and 43 by shearing to produce the narrow openings 44, 45. The arms 46, 47 enable the side arms to be connected to a circular. valve ring, such as shown in Fig. 1.

While I have referred to a valve ring and spring as having separate functions, it will be understood that in such forms as Fig. 3, for instance, the sprin itself may also serve as a valve ring, and t is same explanation in Fig. 1, except that in such event the members 14, 15 would necessarily be given a slight bend so as to engage the top instead of the bottom of the circular side members 11, 12 in order to enable those members-to lie in the same plane as the valve ring 13.

The shape 0 the' spring can be varied widelyand will necessarily be varied if the form of the valve is varied. But in 'order to carry out my invention it is required that the'side members be connected to each end of the central or supporting member so that,

as the springs distort, the motion will be such that there will be no tendency to rotate the valve.

I claim: l

each of said side members having its ends 90 While the circular form shown in various connected with the ends of said supporting member and being otherwise unconnected with sand supporting member, and said valve being connected to said spring only to each of said side members between its ends.
